have you put the guages to it to make sure it has enough freon in it,if it is low the pressure switch will not allow the compressor to come on.if freon is ok,the switch could be bad,try bypassing the switch just to see if comp comes on,if it does it could be an electrical problem..i had this problem on a previous truck one time

I think most conversion kits with the freon can is around $50... but, I was told that you have to change out hoses at the very least. I was also told that you have to purchase all new parts, including compressor. I don't know of any way to flush out / purge any of the remaining R-12 unless you have access to a purge unit. I think that if you get a kit and all new hoses, though, you should be okay.

I didn't replace any parts when I did my conversion to R-134A in my '89 B2. I did have to replace the compressor afterwards due to a clutch problem. I used a compressor from an '87 Ranger. I did all this about 5 or 6 years ago and the system still works great for me.
The reason they say, in most cases, to replace hoses, evaporator, etc., is because there are some vehicles out there that need this done. Older Chrysler products need it done (it figures).
All I needed was to add the high and low port adapters, PAG oil, and then charge the system. The conversion kit at the time was $35. It is probably more now since the cost for R-134A has increased.
